This paper outlines work currently being undertaken to reconstruct submerged archaeological landscapes off the north coast of Ireland. This research uses the recently‐completed Joint Irish Bathymetric Survey (JIBS), which has provided full‐coverage high‐resolution multibeam bathymetric data for the sea‐bed off the north coast. This data has been examined for evidence of past sea‐level change and been used to produce palaeo‐geographic reconstructions of the past landscape, which in turn have facilitated the identification of ten areas of high archaeological potential. The results presented here will form the basis of a future programme of archaeological survey and prospection. © 2010 The Authors 相似文献

This paper reports on the first systematic attempt to conduct archaeological survey and excavation for submerged prehistory on the island of Ireland. Fieldwork was conducted in two small bays where Early Mesolithic flint artefacts washed ashore hinted at the presence of a submerged assemblage. Methods employed include non‐intrusive survey, hand coring and excavation. Together, these allowed identification of the artefact source, albeit reworked, in one bay and an early Holocene peat in the other. Though the subtidal assemblage is reworked and relatively small, it is significant in an Irish context and more widely illustrates the potential preservation of prehistoric sites and palaeo‐landscapes in high‐energy settings. 相似文献

This reports on a project that combined evidence gleaned from aerial photographs, place‐names, interviews, topography, LIDAR data, and sonar bathymetry to locate stone tidal fish weirs in the Molène Archipelago. The results were verified by diver and pedestrian visual surveys. Models of Holocene sea‐level change allowed a group of possibly Late Mesolithic–Early Neolithic weirs to be recognized, with a second group broadly dated to the later Neolithic–Early Bronze Age. The construction of these long megalithic structures is compared to the funerary monuments for which the Molène Archipelago is well known, in terms of technique, cost, and societal organization. 相似文献

We present and test a predictive archaeological survey model that targets early Holocene paleoshorelines in the Prince Rupert Harbour area using LiDAR bare earth digital terrain models and a 15,000-year reconstructed history of relative sea level change. Despite a century of archaeological research in the study area, no sites dating earlier than 6000 cal b.p. had been identified prior to our research. Our field survey identified three early Holocene sites associated with paleoshorelines 7–10?m above current sea level (masl). These locations demonstrate repeated use through the Holocene even as shoreline position changes. We discuss these new data in relation to the early Holocene archaeological record from the rest of the northern Northwest Coast and suggest that the region was ubiquitously occupied by this time and that the lack of recorded early Holocene sites in some areas is likely a result of survey and preservation bias, rather than historical reality. 相似文献

This paper examines the theory and practice of the maritime cultural landscape in general, and projects the theoretical concepts and aspects involved on the highly dynamic late medieval north‐eastern Zuiderzee region in the Netherlands. The cultivation of land and marine erosion (floods and rising sea level) are considered as the main factors that caused the transformation of the physical landscape of this region from peatlands with freshwater basins into a tidal lagoon. As a consequence, multiple settlements drowned, large areas of land submerged, and culture and the landscape gradually became more maritime, giving the research area a cultural identity and dimension. 相似文献

In an area of 400 sq km in the south east Grampians including Glen Esk, Glen Clova and part of Glen Muick the limits of former corrie glaciers, valley glaciers and a plateau ice‐cap with associated outlet glaciers have been mapped. The limits of the former corrie and valley glaciers are often clearly defined by end moraines, boulder‐strewn ground, the down‐valley termination of hummocky moraines and/or the limits of meltwater channel systems, while in suitable locations outwash terraces usually occur. The glaciers are considered to have formed during the Loch Lomond (pollen zone III) Readvance, when new glaciers developed in upland sources following complete ice‐sheet decay. The readvance was accompanied in granite areas by the formation of large solifluction lobes, these lobes being found only outside the mapped ice limits. The interpretations presented are not in accord with those recently given by D. E. Sugden for the western Cairngorms. 相似文献

This paper describes the hitherto unreported occurrence of mid‐Holocene mangrove deposits in the Richmond River estuary, southeastern Australia, thereby providing evidence for changes in the distribution and composition of mangrove communities within a subtropical estuarine system during the Holocene. Stratigraphic, radiocarbon and palynological evidence indicates that widespread development of mangrove communities took place in the upstream reaches of the Richmond River estuary during the period 7000 to 6000 years BP. These communities maintained their habitat through substrate aggradation under the conditions of a moderate sea‐level rise, in contrast to other estuaries within the region, which generally experienced the submergence of intertidal substrates. Mangrove species belonging to the family Rhizophoraceae, most likely Bruguiera gymnorrhiza and Rhizophora stylosa, dominated these communities, in strong contrast to contemporary communities, which are dominated by Avicennia marina. Moreover, these mid‐Holocene communities were located a considerable distance upstream of the contemporary occurrences of Rhizophoraceae species within the estuary. The changes in the spatial distribution and composition of mangrove communities parallel the large‐scale evolution of the estuary driven by sea‐level variation. Shallow, buried Pleistocene terraces probably contributed to the regionally unique aggradational response of the mangrove communities and their substrates to a sea‐level rise during mid‐Holocene times. 相似文献

The excavation in the 1890s of a skeleton of the warm‐water marine mammal Dugong dugon, associated with Aboriginal artefacts, from a Botany Bay salt marsh, marked the beginning of speculation about climate and sea level change in Australia over the period of human occupation. The dugong bones have recently been dated, giving a conventional 14C age of 5520±70 years BP, which is consistent with three older 14C dates for a layer of buried trees that underlies much of the north Botany sediments. The carefully drawn cross‐sections of depositional strata produced by the original discoverers allow further interpretation of the pattern of Holocene sea‐level fluctuations in the Sydney region. Layers of estuarine sediment, such as the one containing the dugong skeleton, are inter‐bedded with peat layers containing in situ roots and stumps, suggesting that the site alternated between sub‐aerial exposure and submergence throughout the Holocene. The presence of the dugong is suggestive of warmer conditions, and its inland location indicates a more extensive Botany Bay in the recent past. This is in agreement with other work from southern New South Wales describing both warm‐water marine species and higher sea levels several thousand years ago.

The main aim of this work is to compare the processes of transition to the Neolithic along the Atlantic coasts of continental Europe. Archaeological data on the late Mesolithic and the early Neolithic in the best known regions (central and southern Portugal, Cantabrian Spain, Atlantic France, the shores of the North Sea, and southern Scandinavia) are discussed. The transition to the Neolithic in Atlantic Europe can be viewed as a relatively late phenomenon, with several interesting particularities. Among those, we point out the fundamentally indigenous character of the processes; the existence of a long availability phase, in which hunter-gatherer groups maintained contact with neighboring agriculturalists and probably were familiar with farming and animal husbandry without applying them in a systematic way; and the later development of megalithic monumental funerary architecture. Finally, the main hypotheses so far proposed to explain the change are contrasted with the available evidence: those that argue that the change derives from economic disequilibrium, and those that opt for the development of social inequality as the fundamental cause. 相似文献

Recent refinements in radiocarbon sampling procedures have enabled a more robust absolute chronology for the Mesolithic in the Rhine–Meuse–Scheldt area of northwest Europe. These refinements have allowed for a new chronological sub-division of the Early and Middle Mesolithic periods. Results of this research have indicated that the Middle Mesolithic period was bound by two Early Holocene cooling events, one at 9300 cal. BP and the other at 8200 cal. BP. These results enable a critical evaluation of the role of chronological precision in the investigation of contemporaneity between abrupt climate change and hunter–gatherer sociocultural change. In this paper we focus on the variable chronological resolution of the Early to Middle and Middle to Late Mesolithic transitions in the RMS area, and the role of this variable resolution in our ability to investigate the contemporaneity of these two transitions with different Early Holocene abrupt cooling events. This paper highlights two central challenges facing archaeological investigations of the relationships between climate and culture change: first, the requirement of tight chronological overlap between climate and culture change events and consideration of leads and lags in ecosystem and subsequent human responses to climate change; second, the equifinality problem and the separation of the impact of gradual from punctuated environmental change on human societies. 相似文献

Predictions of future requirements for the protection of maritime archaeological sites are made using the fetch method which has been developed to evaluate the quality of landing‐places and navigable channels. The very useful method may explain why archaeological sites along the coast are rare in some areas, but numerous in others. Many of them are vulnerable to destruction by the effects of climate change, especially rising sea‐levels, based on the IPCC scenarios. The objective fetch method can be used worldwide to predict where new finds of sites close to sea‐level can be expected, and also to predict a site's vulnerability. 相似文献

The antiquity and context (site or feature type) are the two principal factors that act as a framework for interpreting charcoal and wood data from archaeological sites in the recreation of past woodland environments. This research addresses these parameters through the analysis of over 18,000 charcoal fragments from 57 archaeological excavations carried out along a 61?km road scheme in the midland region of Ireland. Observations on spatial vegetation dynamics and woodland resource patterns are also reported on. The data were analysed through percentage frequency and multivariate analyses. The results reveal woodland resource usage in terms of wood types selected for use as fuel or as structural wood as well as patterns of change and variability in taxonomic composition in relation to site types, feature types and time periods. Selection was found to be low in prehistoric times and in particular at burnt mound sites/fulachta fiadh but became increasingly important as time progressed. This has important implications when charcoal from archaeological settings is used in environmental reconstructions. 相似文献

Since the 1980s, several experimental analyses have been able to differentiate some lithic tool types and some of their raw materials according to the morphology of cut marks imprinted by such tools when used for butchering activities. Thus, metal tool use has been differentiated in contexts with an abundance of lithic tools, or even the use of hand axes has been documented in carcass processing, in contrast with simple unretouched or retouched flakes. As important as this information is, there are still other important aspects to be analysed. Can cut marks produced with different lithic raw material types be differentiated? Can cut marks made with different types of the same raw material type be characterized and differentiated? The objective of this study is to evaluate if cut marks resulting from the use of different flints and different quartzites are distinguishable from each other. In the present work, an experimental analysis of hundreds of cut marks produced by five types of flint and five varieties of quartzite was carried out. Microphotogrammetry and geometric–morphometric techniques were applied to analyse these cut marks. The results show that flint cut marks and quartzite cut marks can be characterized at the assemblage level. Different types of flint produced cut marks that were not significantly different from each other. Cut marks made with Olduvai Gorge quartzite were significantly different from those produced with a set comprising several other types of quartzites. Crystal size, which is larger in Olduvai Gorge quartzites (0.5 mm) than Spanish quartzites (177–250 μm), is discussed as being the main reason for these statistically significant differences. This documented intra‐sample and inter‐sample variance does not hinder the resolution of the approach to differentiate between these two generic raw material types and opens the door for the application of this method in archaeological contexts. 相似文献

Based on a theoretical approach of diaspora theory and the use of ethnographical comparative analysis, it is argued that the early settlement of South Norway probably brought about diasporic conditions. Archaeological and natural science records are applied to discuss the migrations of mobile hunter-gatherers with a shamanistic reindeer culture from the Continent, after deglaciation of the Weichselian ice cap. This paper discusses the diasporic people's identity, their survival as a group, their adaptation to the new environment and the development of an independent reindeer culture characterized by relics and meeting places, after the break in the regular contact between people in the area of origin and South Norway. 相似文献

ABSTRACT Field explorations at the newly recorded Hakaea Beach site, Nuku Hiva, Marquesas Islands were spread across a 12,500 m2 area on the western coastal flat. The site's geomorphic and cultural history is reconstructed based on nine strata and ten radiocarbon determinations. The Hakaea record illustrates the range of powerful environmental processes, including sea level fall, climate change, tsunamis, and tropical storm surges, which have operated on Marquesan shorelines for the last 800 years, and the ease with which past human activity can be obscured or erased. The results highlight the need to systematically search for protected coastal contexts and geomorphic settings where older surfaces might be preserved. Radiocarbon assemblages from the 13th century Hakaea Beach site and seven other early Marquesan sites are considered in light of three models of East Polynesian dispersal: 1) Leap‐frog; 2) Stepping‐stone; and 3) Advancing Wave. Along with chronometrics, the processes and mechanisms which might account for regional patterns of mobility and settlement are emphasized. The Marquesan record is unique amongst central East Polynesian archipelagos in the number of pre‐14th century sites, a pattern that might relate to the antiquity of human settlement, and one which should be considered alongside the late Holocene sea level record. 相似文献

A robust debate among coastal geomorphologists as to the processes by which beach‐ridge plains around Australia have formed was initiated by a former President of the Institute of Australian Geographers. This review gives special consideration to the work of Jack L. Davies, whose academic contributions to coastal geomorphology in Australia have not always been appropriately acknowledged when explaining how similar plains have evolved elsewhere in the world. Davies recognised that relatively steep storm waves caused erosion (cut) on beaches, whereas less steep long‐period swell waves returned sand (fill). He considered the beach berm to be the nucleus on which a beach ridge formed, which could subsequently develop into a foredune, in contrast to cobble ridges that were deposited during storms. Offshore conditions regulate supply of sand to the shoreline, partly through effects on wave refraction, with higher rates of supply where the nearshore is shallow. It was apparent to Davies that the elevation of successive ridges might, but not necessarily, provide evidence of past changes of sea level, despite adornment by variable amounts of windblown dune sand. Morphodynamic understanding of long‐term coastal evolution, based on radiocarbon dating chronologies, has demonstrated that Australian coastal plains formed over the past ~6,000 years when sea level has been close to its present level, in contrast to several documented locations in the northern hemisphere where the sea has been rising for the past few millennia. Particularly insightful were observations by Davies that ridge formation could be influenced by a range of factors including changes in sea level, storminess, or sediment supply. These factors acting singly or in combination seem likely to change in the future. Understanding such responses remains a high priority and can be addressed by new technologies, such as light detection and ranging, optically stimulated luminescence dating, ground‐penetrating radar, and computer simulation. 相似文献

This article describes fieldwork undertaken in 1972 at the harbour of the Hellenistic city of Ptolemais at Tolmeita in Cyrenaica, Libya. This survey has shown that the city possessed a sophisticated Hellenistic harbour installation, now submerged by some 2 m. It consisted of a small fishing harbour and a larger commercial harbour protected by extensive stone breakwaters built around two offshore islands. Between the harbours, remains were found under water of an extensive block‐built quay connected to one island, where there was a system of submerged rock‐cut tanks. These are interpreted as the foundations of a fish‐processing factory. Changes in sea‐level are also discussed. 相似文献

The Early Medieval period in Ireland (c. A.D. 400–1150) has been the subject of much archaeological and historical study. The recent application of various forms of archaeological sciences, as well as palaeoenvironmental studies, to the archaeological record have, however, added fresh impetus to this study area. It seems increasingly evident that significant changes to economy and society occurred during this period and were not recorded in detail in the contemporary documentary sources. This paper will attempt to outline those changes and to assess whether, or to what extent, they were influenced by climate change. 相似文献

This paper presents new 500 year interval palaeogeographic models for Britain, Ireland and the North West French coast from 11000 cal. BP to present. These models are used to calculate the varying rates of inundation for different geographical zones over the study period. This allows for consideration of the differential impact that Holocene sea-level rise had across space and time, and on past societies. In turn, consideration of the limitations of the models helps to foreground profitable areas for future research. 相似文献
